ROTARY PUDDLlNG-FURNACE.

SPECIFICATION forming part of Letters Patent No. 295,751, datedApplication filed June .22, 1883. (No model.)

To aZZ whom, it may concern Be it known that I, Jnssn HALL, J 1a, acitizen of the United States, and a resident of Phoenixville, Chestercounty, Pennsylvania, 5 have invented certain Improvementsin RotaryPuddling-Furnaces, of which the following is a specification. Myinvention consists of certain improvements, fully described hereinafter,in the movable flue-sections between a fixed flue andthe outlet end of arotary, puddler.

In the accompanying drawings, Figure 1, Sheet 1, is a view, mainlyinsection, of a rotary puddler, part of a furnace, and my improvedfluestructure for carrying off the products of combustion to a fixedchimney; and Fig. 2, Sheet 2, an end view of Fig. 1, looking in thedirection of the arrow.

The rotary puddler A, which is supported on wheels carried bya truck, A,in a manner described in another application for a patent, does notdiffermaterially from ordinaryrotary puddlers. There is the usual outershell, a, the inner casing, 12, the water-space c between the two, andthe lining d of refractory material. The inlet-opening c of the puddleris surrounded by'a ring, f, with which coincides a ring, f, surroundingthe outlet 9 of the furnace l5, and the outlet-opening h of the puddleris surrounded by a ring, j, coinciding with a ring,j, atthe entrance zof the flue structure 0. My invention relates to this structure, themanner of introducing water into the space between the two. casings ofthe puddler, of moving the latter endwise and free from frictionalcontact with the furnace, and the mechanism for rotating the puddler andmoving it away from or introducing it between. the furnace and fluestructure being described in another application for a patent. Thepermanent elevated chimney D is built on transverse beams on m, securedto longitudinal beams 01., which aresupported by columns p,- or thechimney may be built on any other available supports or frame-work. Theflue structure 0 is composed of the outer casing, q, the in, ner casing,75, and the refractory lining 'v, water being introduced into andcirculating with in the space between the two casings. The

flue O is pivoted toor loosely suspended from March as, 884.

thechimney-supporting structure, links K K, as shown in Fig. 2, being inthe present instance used forthis purpose, the links being adapted tohooks s 8, one of which is secured to each edge of the flue. The linksare preferably inclined, as shown, the threaded ends of the upper linksbeing provided with nuts, by turning which the flue can be so adjustedthat its entrance i may coincide with the outlet-opening of the puddler.To a suitable 6o foundation are secured standards E E, through whichpass set-screws F F, carrying at their ends plates as, which, byadjusting the screws, are caused to bear against the rear of the fluestructure, so thatthe front end of the latter can be moved as close tothe rear end of the puddler as the desired free rotation of thesame'will permit. The suspension-links are attached to the fluestructure at such a point that when it is relieved from the pressure ofthe screws it will recede from the end of the puddler and permit thesame to be withdrawn from between the furnace and flue structure. Thus,if the hooks to which the links are con nected are at the point y, thepreponderance of the front portion of the structure will induce the sameto move away from the end of the puddler when the flue is relieved fromthe pressure of the screws. The upper end of the flue structure shouldbe as close to the lower end of the fixed chimney as the required slightmovement of the flue structure will permit. At the back of the saidstructure is an opening provided with a suitable door, in which is apeep-hole for the inspection of theinterior of the puddler.

I am aware that a movable flue-section has been combined with andinterposed between the outlet end of a rotary puddler and a fixed flueor chimney. This, therefore, I do not claim; but

' I claim as my invention 1. The combination of the puddler and a fixedvertical chimney, open at the bottom, with the pivoted or suspended fluestructure 0, having an opening at the top communicating with the saidchimney, and a lateral opening communicating with the outlet of thepuddler, all substantially as set forth.

2. The combination of the fixed chimney, I00
